CoordinateConversion format to show DMS + elevation

Leandro-Zamudio — Tue, 27 Dec 2022 14:42:02 GMT

Hi, following the CoordinateConversion custom format in the documentation I've implemented the widget correctly in my 4.24 app.

But now i need to show the lat/long in DMS, it's like combining these two

This is my format code

Note: The Z value is divided by 2 because the WebScene has a 2x exaggeration.

Thanks in advance

Hi @Leandro-Zamudio

In such a case, it is the best to break the coordinates already into degrees-minutes-seconds inside the conversionInfo and adjust the coordinateSegments accordingly.

For pre-formatting the point's coordinates into "40 50 02.55N 121 31 54.83W" pattern, you can use the coordinateFormatter converter:

coordinateFormatter.toLatitudeLongitude(returnPoint, "dms", 3)

Here's an example app that shows the widget with a custom DMS format with Z values: https://codepen.io/gsoosalu/pen/xxJRjMX

Hope this helps you further.

Hi @GreteSoosalu

I watched the codepen but it doesn't show the custom coordinate format but reading the code and re-thinking it I could solve it breaking the coordinates as you suggested. For further reference I share the solution of the same code but corrected:

I'd like to know more about the Regular expressions that you used to find a number, is there any reference to read about it?

// Regular expressions to find a number const numberSearchPattern = /-?\d+[\.]?\d*/; const number2Digit = /\d{1,2}[\.|\.]?\d*/i; // Same as CoordinateConversion widget's DMS format uses const number3Digit = /\d{1,3}[\.|\.]?\d*/i; // Same as CoordinateConversion widget's DMS format uses

Thanks for your help

Oh, you're right, there was a bug in my app. It should be fixed now, so the custom format should be shown:

And thanks @Leandro-Zamudio for sharing the fixed code that works for you!

Regarding the Regular expressions, I cannot think of any references at the moment but if I find anything, I'll post it here.
